Detailed explanation-1: -> Non reducing sugars-A non-reducing sugar has no free carbonyl groups. They are in acetal or ketal form. These sugars do not show mutarotation. Common examples for these are Sucrose, raffinose, gentianose and all polysaccharides.
Detailed explanation-2: -Answer: Stachyose, Sucrose, Verbascose, Trehalose and Raffinose are the five examples of non reducing sugars. Carbohydrate: A carbohydrate can be defined as a biomolecule that owns the atoms of hydrogen, oxygen and carbon. A carbohydrate usually contains hydrogen and oxygen atoms in the ratio of 2:1.
Detailed explanation-3: -Only sucrose is a non-reducing sugar as it does not reduce Tollen’s reagent (due to the absence of −CHO group).
Detailed explanation-4: -Sucrose is a non reducing sugar due to 1-2 linkage. Due to this linkage, both aldehyde group of glucose and keto group of fructose are not free. Hence, the sugar becomes non reducing. Was this answer helpful?
Detailed explanation-5: -Examples of reducing sugar is galactose, glucose, glyceraldehyde, fructose, ribose, and xylose.
